Specification of Letters Patent.

Patented July 6, 1909.

To all whom it may concern:

Be it known that I, EDWARD O. Goss, a cltlzen of the United States, residing at Waterbur in the county of New Haven and coiling metal, and more particularly to an attachment for a sheetmetal rolling machine.

The object of the invention is to provide an attachment for a rolling-mill for rolling sheet metal, whereby the metal may be taken directly from the rolling-mill and automaticall coiled or blocked into suitable coils or ro ls.

The invention consists essentially of mechanism for stripping the metal from the rolls and guiding it thence to a coiling or blockin mechanism, mounted upon a carriage whic is capable of being moved toward and from the strippin mechanism, the coiling or blocking mec anism being actuated to form an initial lap of metal on its winding-drum as it comes from 'the rolls and coil it upon the drum, without direct handling of the metal by the operator, and then loosen up the coil so that it may readily be removed from the winding-drum, all as Iv will proceed now more particularly to set forth and finally claim.

In the accompanying drawings, illustrating the invention, 1n the several figures of which like parts are similarly designated, Figure 1 is a side elevation, showing the Winding-drum and its guiding-pulleys and belt in dotted lines in its forward position to receive the metal from the rolling-mill. Fig. 2 is a top plan view with the carriage in its rearmost position. Fig. 3 is a top plan view in partial section, on a larger scale, showing the gearing for operating the carriage, winding-drum, and attachments. Fig. 4 is a transverse section, on a lar er scale, taken substantially in the plane ofline A B, Fig. 2, and looking in the direction of the arrow, some of the parts being omitted for clearness. Fig. 5 is a transverse section, on

plane of line C D, Fig. 2, and also looking in the direction of the arrow, some of the parts being omitted for clearness. 6 1s a levers for reversing the winding drum. Figs. 7 and 8 are respectively a plan and an end elevation showing the cam and escapement clutch for shifting the belts and their supporting-pulleys and arms to one side of the winding-drum. Fig. 9 is a top plan view of the sliding clutch-block. Fig. 10 is a longitudinal section of the cam and escapement-clutch. Fi 11 shows in plan view the escapement-c utch operating-levers separated. Fig. 12 is an elevation, partly in section, showing the manner of mounting the escapement clutch-levers. Fig. 13 is a side elevation of the escapement-clutch levers. Fig. 14 is a plan view of the tension relieving clutch and its operating connections.

F igs. 1 and 2 show the guide-rods, rack bar and power-shaft broken out to bring the views within the sheet. These parts may be constructed of any length to extend the required distance from the rolling-mill.

1 and 2 represent the rolls of any ordinary sheet-metal rolling mill, and 3 a portion of the frame thereof.

Attached to the frame of the rolling-mill in front of the rolls is a rock-shaft 4 mounted in suitable bearings 5 secured to the frame in suitable manner. A hand-lever 6 is secured to one end of said rock-shaft and is provided with a spring-pawl 7, adapted to engage a rack-bar 8, sup orted u on a bracket secured to the frame 0 the rol ing-mill, to maintain said lever in its adjusted positions. Arms 9, carrying rollers 10 at their outer ends, are connected with the rock-shaft 4 and project toward the rolls 1' and 2 and are adapted to be moved by said rock-shaft through the movement of the hand-lever 6. Also mounted in suitable bearings 11 upon the frame of the rolling-mill are rock-shafts 12 and 13,

rovided with upwardly-projecting arms or evers 14 and 15, having at their upper ends flattened friction or contact-surfaces 16 and 17, the arms or levers 14 and 15 being so arranged upon their respective shafts with relation to each other that their contact-surfaces will lie in the path of movement of the rollers 10, and will normally remain open a sufficient distance to receive the rollers 10. Also fixed upon the rock-shafts 12 and 1 3 are guidelates 18 and 19 projecting horizontally rom the rock-shafts and having their outer ends shaped to fit snugly against the rolls of the rollmg-mill, the said guide-plates 18 and 19 being spaced apart sufficiently to 1 otherwise secure permit the passage of the metal between them as it is stripped from the rolls by the edges of said lates. Preferablythe ideplates 18 an 19 are shod with too steel pieces 20 and 21 at their points of contact with'the rolls of the rolling-mill, to prevent the wearin away of said plates.

Arrange to one side of the rolling-mill and sup orted in any suitable manner, as by standar s 22 and 23, bolted or otherwise secured to the floor of the building, are guide-rods 24 and 25.

Mounted to slide back and forth upon said guide-rods 24 and 25 is a carriage 26 adapted to carry all of the mechanically-driven parts of the coiling mechanism and also the automatic mechanism for moving the carriage toward and from the rolling-mill.

A shaft 27 is arranged parallel with the guide-rods 24 and 25 and mounted in suitable bearin s 28 and 29 in the standards 22 and 23, an has secured to it at one end a pulley 30 which may be driven by a belt rom a 'countershaft or any other source of ower.

The shaft 27 is grooved longitudinally to receive feathers or splines on the clutchmembers, hereinafter referred to whereby said clutchmembers may be moved along the shaft by the carriage with the other parts of the o crating-mechanism.

A rac -bar 31 is stationarily supported, in any. suitable manner, in the standards 22 and 23 in parallelism with the guide-rods 24 and 25, and is adapted to be engaged by a spur-gear, hereinafter referred to, carried by t e carriage to move the carriage back and forth upon the guide-rods.

Mounted in suitable hearings in the carria e 26, above the guiderods 24 and 25, is a s aft 32, carrying a block or winding-drum 33 at its outer end beyond the carriage, and in alinement with the rolls 1 and 20f the rolling-mill, and fixed to shaft 32 adjacent to the front side of the carriage, is a spurgear 34.

Supported in suitable hearings in a substantially U-sha ed bracket 35, bolted or to the underside of the carriage 26 is a counter-shaft 36, having a s urgear 37 foosely mounted thereon and'mes g with the gear 34 on the winding-drum shaft 32. Mounted .on one end of said countershaft 36 and fixed thereto is a bevel-gear 38 adapted to be engaged by one or the other of bevel-gears 39 and 40, loosely mounted u on the power-shaft 27, a sliding clutch-mem her 41 being s linedto said power-shaft 27 between sai ears 39 and 40, whereby one'or the other 0 said gears may be locked with and rotated bythe power-shaft. The gears 39 and 40 are rovided wlthintegral grooved collars 42 an 43, respectively, adapted to be' engaged b forked brackets 44-and 45 bolted to and epending from the carriage 26,

whereby the gears 39 and 40 are maintained in position u on the moved alongt e shaft urin the movements of the carriage toward and rom the rollingmill. A foot-lever 46 is pivotally mounted upon a stud 47 projecting from the bracket 35, and has its treadle-portion' extending outwardly in convenient reach of the foot of the operator. At its other end said footlever 46 is connected by means of a link 48 with a bell-crank lever 49, mounted upon a stud 50, secured to the bracket 35, and having the forked arm 51, Figs. 5 and 6, adapted to engage a groove in the clutchmember 41, whereby the said clutch-member may be shifted into and out of engagement with one or the other of the bevel-gears 39 and 40. A coiled spring 52 is connected at one end to the bracket 35 and has its other end connected to the foot-1e ver 46, to maintain said footlever in an elevated osition and normally hold the clutch-member 41 in engagement with the bevel-gear 40, whereby the windingdrum is rotated in the proper direction for coiling the metal.

The spur-gear 37 which, as heretofore stated, is mounted loosely on counter-shaft 36, is provided. with an integral flange 53, and mounted to slide upon the shaft 36 is a grooved collar 54 to which are pivoted oppositely arranged links 55, which are connected at their other ends to the operating connections 56 of sliding clutch-shoes 57, adapted to engage the eriphery of the flange 53 of the gear 37. he clutch-shoes 57 are slidably mounted, as by dovetail connection 58, in a collar 59, fixed to the shaft 36. Supported in a bearing 60 projecting from the side of the U-shaped bracket 35 is a short vertical rock-shaft 61 having fixed to its upper end a forked lever 62, preferably provided with friction rollers 63, adapted to engage the grooved collar 54, a lever 64 being fixed to the lower end of said rock-shaft 61 having its other end pivotally connected to a link 65, which in turn isconnected by a slot and pin connection with a lever 66 projecting outwardly' and provided with a suitable u turned handle 67 in convenient reach of tffe operator.- The lever 66 at its other end is connected to a rock-shaft 68 mountedin a ower-shaft and also suitable bearing 69, formed in a bracket 70, I

-described, to engage'and disengage the flange 53 of the gear 37 Mounted in suitable hearings in the carriage 26 are rock-shafts 71 and 72 anda driving-shaft 73. These shafts 71, 72 and 73 are mounted to slide longitudinally in their bearings in the carriage, and are connected to move simultaneously by a plate 74- fitted upon said shafts between the walls of the carriage 26 and held in proper position upon the shafts by means of fixed collars 75, 76,'and 77, arranged upon the respective shafts on op osite sides of the plate.

ixed to the outer ends of the rock-shafts 71 and 72 are arms 78 and 79, respectively, having belt-pulleys 80 and 81 mounted upon their outer ends, the said pulleys 80 and 81 being preferably rovided with central flanges 82 and 83. ecured to the arm 78 in any suitable manner, is a curved guide-plate 84, see Fig. 1.

Fixed upon the rock-shafts 71 and 72 toward the carriage 26 are segmental gears 85 and 86, adapted to mesh one with the other for the purpose of transmitting power from one shaft to the other to cause the arms 78 and 79 to move toward and away from the winding-drum. I

Secured to the outer end of the shaft 73 is a belt-driving pulley 87, similar in construction, to the pulleys 80 and 81, and arran ed in alinement therewith. A belt or pre erably two belts 88 are arranged over the pulleys 80, 81 and 87, and an suitable mechanism for tightening the be ts about the driving-pulley 87 may be provided, and I have herein shown two oppositely arranged bellcrank levers 89 and 90 loosely mounted upon the shaft 73, one of the arms of each of said levers projecting from the shaft upon opposite sides and in substantial alinement w1th each other, and provided with idler or belttightening pulleys 91 and 92, adapted to press the belts 88 about the pulley 87 and thus prevent the tendency of said belts slipping, and also taking up any stretch that may occur in saidbelts. A coiled spring 93 is connected to the ends of the other arms of said bell-crank levers which tends to draw said arms toward one another,-a nd thereby maintains a continuous pressure of the idlers or pulleys 91 and 92 upon the belts 88.

Pulleys 94 and 95 are arranged upon the winding-drum shaft 32 and the shaft 73, respectively, to turn with them, and a belt 96 is arranged upon said pulleys, whereby the power from said winding-drum shaft is transmitted to the belt-driving shaft 73 and its attached pulley 87.

Secured to the rock-shaft 72 is a wormwheel 97, ada ted to be engaged by a worm 98 fixed on t 0 end of a short horizontal shaft 99, suitably supported in aybracket 100 fixed 'to the base of the carriage 26 and having a bevel-pinion 1-01 fixed to its opposite end, meshing with a bevel-gear 102, secured to the upper end of a vertical shaft 103, mounted in suitable bearings in the carriage 2'6 and at its lower end in a bracket 104, bolted or otherwise secured to the underside of the carriage. Mounted upon the vertical shaft 103 is as ur-gear 1'05 meshing with the rack-bar 31, w ereby the carriage is moved back and forth as hereinafter explained.

ed upon the power-shaft 27. The bevel- 7 gears 111 and 112 are provided with integral grooved collars 113 and 114, adapted to be engaged by forked brackets 115 and 116, bolted or otherwise secured to and depending from the carriage 26, whereby said gears are maintained in position u on the shaft, and also adapted to be move along the shaft in the movement of the carriage to and from the rolling-mill.

A clutch-member 117 is splined to the shaft 27 between the gears 111 and 112, and is adapted to be thrown intoengagement with corresponding clutch-faces on one or the other of the gears 111 and 112, to lock one or the other of said gears to the power-shaft to thereby transmit motion to the shaft 108 in the desired direction.

Secured to the upper end of the rock-shaft 68 in bracket 70, is a forked lever 118, provided with suitable friction-rollers adapted to engage a groove in the clutch-member 117. Thus it will be observed that by shifting the hand-lever 66, which is connected to the lower end of the rock-shaft 68, the clutch-member 117 ma be shifted in either direction to effect the ocking of one or the other of the gears 111 and 112 to the powershaft.

Fixed to the shaft 73 is a grooved collar 119, and extending from the carriage to one side thereof is a bracket 120 in which is mounted a vertical rock-shaft 121. A forked lever 122 is fixed to the upper end of shaft 121 and is rovided with suitable friction-rollers 123 a apted to engage the groove of the collar 119 on shaft 73. Secured to the lower end of the rock-shaft 121 is an arm 124 projecting toward shaft 27, and provided at its outer end with a suitable frictionroller 125, adapted to engage cam-groove 126 in a cam 127 fitted loosely upon shaft 27. The ca-m127 is also provided with a straight groove 128, and a recess 129 which extends across said groove 128 and opens at the face of the cam. A sliding clutch-block 130 is fitted in said recess 129 and is backed by a spring 131 in the inner end of said recess. The clutch-block 130 is provided with a transverse bevel-sided notch 132 coinciding with the straight groove 128 in the cam 127. Pivotally mountedupon a stud 133 secured to a suitable bracket 134, bolted or otherwise seouredto the carriage 26, are two escapement or clutch-operating levers 135 and 136, shaped to fit within the straight groove 128 in the earn 127, and having their ends so shaped "or tapered,-as shown in Figs. 7

and 11, as to alternately disengage and engage the notch 132 in the sliding clutch-block 130, durin the rotation of the cam, to cause the said 0 utch-block 130 to be projected from the face of the cam by the action of its spring 131, and to be retracted into its recess by the action .of one or the other of the clutch-levers 135 and 136 during every half revolution of the cam. The clutch-lever 135 is provided with a roller 137 adapted to' be engaged by a cam 138 fixed to the stationary rack-bar 31, when the carriage is about to reach its farthest position away from the rolling-mill. Splined to the shaft 27, adj acent to the cam 127, is a collar 139 having in. its face next to the cam a radial groove or notch 140 adapted to be engaged by the clutch-block 130 when rojected from the cam upon being released y the action of the cam 138, and thereby locking the cam 127 to the shaft 27 to rotate the same a half revolution when the clutch-block will be retracted and the rotation of the cam stopped for a purpose resently explained. The cam 127 and co lar 139 are held in place upon and moved along the shaft 27 by the engagement of the arm 124 and its roller 125 and the escapement or clutch-levers 135 and 136 with their respective grooves in the cam 127, the collar 139 being arranged adj acent to the grooved collar 114 of the gear 1 12.

Depending from the rack-bar 31 is a bracket 141 having in its lower end an ad justable stop-screw 142, arranged in the path of movement of the hand-lever 66, and in Such position that as the carriage a proaches its farthest osition away from t e rolling-mill, the said ever 66 will strike said stop-screw 142 and be shifted thereby and thus throw the clutch-member 117 out of engagement with the gears 111 and 112, and thus stop the carriage-o crating mechanism,

when the carriage reac es the desired distance away from the rolling-mill.

ad'ustable stop-screw 143 is fixed to the stan ard 23 in the ath of movement of the projecting end of thelink 65, and when the carrialgle reaches its pro er position at the rolling-m' the end of the ink strikes said sto -screw 143 and throu h its connection wit the hand-lever 66 shifizs said lever, and thereby throws the clutch-member 117 out of engagement with gears 111 and 112 and thusstops the carriage-feeding mechanism. The operation is as follows: When the carriage and its attached parts are in the position shown in full lines Fig. 1, and power applied to pulley 30 to turn it in the directlon of the arrow, Fig. 2, the several parts of the coilin -mechanisrri, except the windingdrum, w' remain motionless, and the arms 78 and 79 and their attached pulleys and belts will assume the position shown in said Fig. 1. When'it is desired to coil a stri of metal as it comes from the rolls 1 and 2 0 the rolling-mill, the operator throws the handlever 66 to the right, thus throwing the clutch-member 1 17 into engagement with the bevel-gear 111, caus' sai bevel-gear to turn with the power-s aft 27 and thereby rotating shaft 108 and its worm 107 through bevel-gear 110, and through worm 107 and worm-wheel 106 rotating vertical shaft 103 and its attached spur-gear 105, and said spur-gear 105 meshing with the rack-bar 31, t e carriage will be moved toward the rolling-mill. During the movement of'the carriage in this direction, the rock-shaft 72 will be actuated through its worm-wheel 97, worm 98, shaft 99, bevel-gear 101 and bevelgear 102. By this movement of rock-shaft 72, the arms 78 and '79 and their attached pulleys and belts will be simultaneously-shifted, through the segmental gears 85 and 86, to the position indicated by dotted lines at the right in Fi 1, with the belts 88 partially surrounding t e winding-drum 33 leavin sufficient opening between the uileys an belts in alinement with the exit 0 the rollingmill rolls for the passage of the metal therebetween. When the carria e reaches this dotted line position, the en of the link 65 strikes the stop-screw 143 and automatically shifts hand-lever 66 and thus throws clutchmember 117 out of engagement with gear 111 to a neutral or middle position, and thus stops the carriage feed mechanism. The lever 6 of the stri ping and id attachment is pulled to t e right, an thus orces the rollers 10 in between the friction-surfaces 16 and 17 of levers 14 and 15, and by the movement of the rock-shafts 12 and 13, the uidelates 18 and 19 are forced close up to t e ro ing-mill rolls and effectually strip the metal therefrom and overcome the tendency of the metal to cling or adhere to the surface of the rolls, and consequently guide the metal to the coiling mechanism. The winding-drum 33 is rotated in the proper direction through its gear 34, gear 37, clutch-members 57, shaft 36, bevel-gear 38, and bevel-gear 40 from the power-shaft. The belt 96 and ulleys 94 and 95 connectin the windingrum shaft 32 and pulley sha t 73, transmit the motion from sald winding-drum shaft to the said ulley shaft, and said pulley shaft and the belts 88 applied thereto are driven at a surface speed a little faster than the s eed of the metal bein wound on the win ing-dr'um, and the be t-tightening pulleys 91 and 92 maintain the proper engaggment of the belts 88 with belt-pulley 87. the metal leaves the guides or strip ers, it is uided in between the pulleys 80 and 81 and etween the belts 88 and the underside of the winding-drum 33, and passes around the drum between the belts and drum, and its end strikes the curved (guide-plate 84 and will be automatically an without the operator s intervention guided thereby in between the winding-drum rolling-mill rolls after the first lap and the first layer of metal as it comes from the guides. This forms the first lap of metal about the winding-drum, and it now becomes necessary to move the carriage away from the rolling-mill in order to inspect the metal as it comes from the rolling-mill, and to effect this movement of the carriage, the operator throws the hand-lever 66 to the left and thereby shifts the clutch-member 117 into engagement with the bevel-gear 112 on the power-shaft, thus reversing the gearing heretofore described for moving the carriage to its forward position and returni the carriage to its rearward osition, an also returning the (guiding-be ts and their supporting arms'lan pulleys to the position shown in full lines in Fig. 1.- As the carriage approaches its rearmost position, the lever 66 will strike the stop-screw 142 and will be retardcd in its movement with the carriage, and by the movement of the lever 66 the clutch-member 117 will be thrown out of enga ement with the bevel-gear 112 to a neutra or middle position, and the movement of the carriage stopped at the end of its travel.

When the carriage starts away from the of metal is wound upon the Winding-drum, it becomes necessary to relieve the tension on said metal, due to the pull of said winding-drum. In this connection it is to be noted that the same mechanism drives the winding-drum at all times and in all positions, and when the winding-drum has reached its back position, and is completing the last laps of the coil of metal, the surface speed of said metal in feet per minute is different than when the winding-drum is starting from its forward positlon, and during this movement the drum has the combined operations of winding the coil and at the same time pulling against the metal. To relieve this tension on the metal, the pressure of the clutchshoes '58 on the flange 54 of thegear 37 is slacked when the operator throws the handlever 66 to the left in starting the return movement of the carriage. By this movement of the hand-lever 66, the pin connection in said lever 66 engages the left-hand end of the slot in link 65, thereby pulling upon lever 64 and through forked lever 62 and its operating connections shifting clutchcollar 54 to thereby slacken the pressure of clutch-shoes 58 on the flange 53 of gear 37, and since said gear 37 is loosely mounted on shaft 36 and is driven by said clutch-shoes 58, the slacking of the pressure of said clutchshoes will allow the gear 37 to slip on said clutch-shoes when the increased tension on the metal occurs due to the combined motions of the carriage and winding-drum. The slipping of the gear 37 will cause said gear to drive the wlndin -drum only fast enou h to maintain a slig t tension on the metal as it comes from the rolling-mill, and

just sufiicientto hold the first lap of metal on the winding-drum, during the movement of the carriage from its forward osition to its back position. As the carriage approaches its back position, the end of link 65 will strike the stop-screw 142, and the clutch-mechanism will be reversed and the full pressure of the clutch-shoes again applied to gear 37 to drive the winding-drum at normal speed to finish the windin of the coil, and u on further movement 0 the carriage, the ever 66 is moved by stopscrew 142 and the clutch-member 117 of the carriage feeding mechanism shifted to stop the carriage as hereinbefore described.

The slot and in connection between the lever 66 and lin 65 ermits the throwing of the lever 66 to the rlght for again starting the carriage in its forward movement, without moving the link 65, and thus the pressure of the clutch-shoes 58 on flange 54 of gear 37 is not affected by the movement of the lever 66, and remains constant so as to drive the winding-drum at normal speed, until said lever 66 is shifted to the left to cause thebackward movement'of the carria e.

When the carriage reaches its back position, the cam 138 on rack-bar 31, strikes roller 137 on clutch-lever 135, thereby rocking the clutch-levers 135 and 136, and thus withdrawing the end of clutch-lever 136 from the notch 132 in clutch-block 130, and depressing the end of clutch-lever 135 into the path of movement of the clutch-block 130. The clutch-block 130 being thus released is forced by its spring 131 into engagement with the groove 140 in collar 139, and the cam 127 thereby locked to the shaft 27 and rotated thereby. As the earn 127 is rotated, its cam groove 126 moves arm 124 to the left and through rock-shaft 121, forked lever 122 and its connection with fixed collar 119 on shaft 73, moves said shaft 73, and also rock-shafts 71 and 72, through the connecting-plate 74, transversely of the carriage, thereby moving the guide-belts and their supporting arms and-pulleys toward the carnage end of the wind1ng-drum, 1n order that the operator may more easily handle the finished coil of metal upon the drum. When the cam 127 has made a half revolution, the beveled end of clutch-lever 135 engages the notch 132 in clutch-block 130 and retracts said clutch-block and dlsengages-it from collar 139 and thus stops rotation of cam 127. When the carr1a e is started in its movement toward the rol mg.- mill, the roller 137 on clutch-lever 135 leaves cam 138, and .the clutch-levers return to their normal position, the clutch-lever 1 35 releasing clutch-block 130 and permitting it to a ain jump into engagement wlth the notch 1n collar 139, where y the cam 127 supporting arms and pulleys to their erative position over the windln -druI n.

the cam 127 has made anot or half revolution, the tapered end, of clutch-lever 136 engages the notch in clutch-block 130 and disengages it from collar 139 and again stopsrrotation of the cam 127.

After the metal has been wound upon the windin -drum to form a finished coil, it is found t at the coil is wound too tight to be easily removed from the drum, and to overcome this difficulty, provision is made for artially unwinding the coil, enough to oosen it, so that it may be readily drawn off the drum. When the end of the metal being wound upon the drum leaves the rollingmill, the 0 erator places his hand u on the coil, and w en the coil is finished, he t en de-' presses the foot-lever 46 and through link 48 and bell-crank lever 49, disengages the clutch-member 41 from bevel-gear 40 and moves it into engagement with bevel-gear 39, thereby reversing the winding -drum driving-mechanism and rotating the winding-drum in the op osite direction, thus loosening the coil, W ichmay then be removed readily from the drum by endwise movement thereof. The foot-lever is then released and the clutch mechanism reversed to again reverse the winding-drum mechanism to rotate the drum in the ro er direction for winding or coiling a f nes strip of metal.

The several operations of the machine, as thus described, are repeated in each movement of the carriage toward and from the rolling-mill in winding successive strips of metal, and as the carriage moves u on the guide-rods, the several members of t e gearing and their controlling mechanism for operating the parts of the winding-mechanism and for feeding the carriage are simultaneously carried along the power-shaft with the carriage by means of the brackets secured to ghe carriage and engaging the several memers.

It is to be further noted that in the operations of first applying the strip of metal as it comes from the rolling-mill to the windingdrum or block, there is no necessity for the operator to handleThe metal at all, but the o eration of applying the stri initially to t e drum or block, as well as t roughout its successive coils, is performed automatically, 5 and hence the danger of injury to "the operator, incident to the old way of manually applying the initial coil to the drum or block is overcome, and conseqliliently the work may I proceed not only wit greater safety, but 60 more expeditiously. Further, the guiding mechanism for a plyingv the strip to the drum is of such 0 aracter as to insure the uniform coiling of the strip upon the drum. While I haveherein shown and described suitable mechanism for carrying out the principle of the invention, it is to be understood that the invention is not limited to the single illustration shown, but is obviously susceptible of variations and modifications, as I mean so to claim the invention.

What I claim is 1. In a machine for coiling metal, the combination of a reciprocating carriage, a winding-drum carried thereon, a blocking device and controlling mechanism therefor operated by the movement of the carriage to lap the leading end of the metal strip upon said drum, and means to effect and control the movements of the carriage in the formation of the first and subsequent laps.

2. In a machine for coiling metal, the combination of a pair of rolls, a carriage adapted to be moved toward and from the rolls, means for coiling a strip of metal mounted on said carriage, means for operating the carriage to move it toward and from the rolls, and means operated by the carriage for controlling the carriage o crating means.

3.
